在本实施方式中，所述第一信号传输板110及所述第二信号传输板120与所述液晶显示面板20的阵列基板不共面。
请参阅图2，图2为本发明第二较佳实施方式的液晶面板驱动电路的结构示意图。本实施方式与第一实施方式不同的是，在本实施方式中，所述原始Gamma电压信号经由所述第一信号传输板110传输至所述第一数据驱动芯片 140(1)，所述原始Gamma电压信号经由设置在液晶显示面板20的阵列基板的非显示区的走线210传输至第二数据驱动芯片140(2)及第N数据驱动芯片140(N)。所述液晶面板驱动电路10还包括N个间隔设置的柔性膜150。N个所述柔性膜150与N各所述数据驱动芯片140一一对应设置，所述柔性膜150用于承载与所述柔性膜150对应设置的数据驱动芯片140，且承载第一数据驱动芯片140(1)的柔性膜150还用于电连接所述第一信号传输板110与所述第一数据驱动芯片140(1)，以将所述原始Gamma电压信号经由所述第一信号传输板110传输至所述第一数据驱动芯片140(1)。

请一并参阅图3，图3为图2中I处及II处的放大结构示意图。在本实施方式中，所述第一数据驱动芯片140(1)内设置第一放大器160a，所述第一放大器160a用于对所述第一数据驱动芯片140(1)接收到的所述原始Gamma电压信号在传输过程中进行补偿增强。所述第(N-M+1)数据驱动芯片140(N-M+1)内设置第二放大器160b，所述第二放大器160b用于对所述第(N-M+1)数据驱动芯片140(N-M+1)接收到的所述原始Gamma电压信号在传输过程中进行补偿增强。在本实施方式中，第(N-M+1)数据驱动芯片140(N-M+1)为第四数据驱动芯片140(4)。
